Infanta Margarita has uses this tiara on several occasions, with or without pearls, but its origin is unknown. Infanta Pilar has the sapphire tiara made from a bracelet and gift from her parents for her 18th birthday, this tiara may have a similar origin.

It is really a nice peace. Pity that it doesn't belong to the main branch as it would be a nice change to all the diamond and diaomdond and pearl pieces they have. Have read somewhere that it has belonged to the mother of the Countess of Barcelona.
